e e CAQSE DESCRIPTION (cont'd) operating properly. The operating electrical current values were well within normal parameters. The valve was disassembled but no apparent damage, corrosion, indication of binding or other abnormal condition was observed. The valve was reassembled and tested satisfactorily. There apparently was some small debris in the valve seat area that created the initial problem. Currently no mechanical or electrical problem exists and no further action is contemplated.
